If you have ever shut down an entire production line just because of a missing liner, you know this: choosing the right crusher parts manufacturer matters more than simply chasing price. The global supply landscape can generally be divided into three categories:

• OEM Manufacturers — Provide original designs and official upgrade solutions, with some also absorbing legacy brands.

   

• Aftermarket Manufacturers — Supply across multiple brands, offering flexible alternatives and custom solutions.

   

• Legacy Brands — Although the OEM has been discontinued or merged, their machines are still running and rely on aftermarket or successor OEMs for support.
  

Because these paths overlap, procurement decisions become complex. To help you navigate, let’s start with OEMs — they set the benchmark of the industry, where you get original designs, complete chamber profiles, and official upgrade kits.

1. Metso

Metso’s parts system is considered one of the most comprehensive in the industry.

Through its online parts system, buyers can directly locate part numbers, whether wear parts or spares (main shafts, eccentric bushings, gears, hydraulic components).

For wear parts, Metso provides tiered products: O-Series (economic replacements), Expert/Max series (extended life), and X-Series (covering third-party machines). Among them, MX hybrid liners are the core innovation, embedding ceramics into the metal matrix to extend life by 1.5–2×.

Combined with over a century of crushing experience and a global service network, Metso offers complete chamber optimization and efficiency solutions.

2. Sandvik Rock Processing

Sandvik’s parts cover both wear parts and spares, including frames, bearings, and hydraulic cylinders.

Its core advantage in wear parts is high-manganese alloys and precise chamber design, with full compatibility with automation systems.

The representative Optitooth™ jaw plates extend wear life by ~30%, increase capacity by ~20%, reduce fuel consumption, and improve product gradation. This makes Sandvik not only a crusher wear parts manufacturer, but also a system efficiency optimizer.

3. Astec (incl. Telsmith)

Astec is notable for complete coverage of legacy models. Its parts catalog includes wear parts and spares, while continuing OEM supply for Telsmith, KPI, and others, plus retrofit kits. These kits upgrade hydraulics and safety systems, extending the service life of older machines. For aggregate plants, this means running equipment longer instead of scrapping prematurely.

4. Terex (MPS, Powerscreen)

Terex also covers wear parts and spares. Its modular design gives many mobile machines (especially Powerscreen) cross-model compatibility, making fleet-wide spare parts management easier.
For wear parts, Terex offers multiple alloy options, allowing buyers to balance wear resistance and toughness. Terex MPS also supports legacy El-Jay equipment with OEM spares, maintaining the serviceability of old models.👉 Terex Spare & Wear Parts

5. Weir Minerals & ESCO

Weir supplies not only wear parts but also common spares (backing rubber, bushings, bolts, etc.). Its unique value lies in ESCO’s proprietary alloy formulas — tailored “recipes” balancing life and toughness.

Wear parts cover jaw, cone, and impact crushers, combined with geometry optimization and engineering services to significantly extend liner life and reduce downtime. These solutions are ideal for high-abrasion ores, helping large mines cut costs per ton.

6. Thyssenkrupp

Thyssenkrupp supplies full parts coverage for gyratory and Kubria® cone crushers, including wear parts and spares.
The strength of its wear parts lies in high precision and safety, designed for demanding heavy-duty operations. In addition, Thyssenkrupp offers performance upgrade kits and digital twin simulations to support chamber optimization and efficiency improvement.👉 Thyssenkrupp Kubria® Cone Crushers

7. KLEEMANN (Wirtgen Group)

KLEEMANN focuses on mobile crushing and screening plants. OEM parts include wear parts and spares, deeply integrated with its control systems.
Wear parts are linked with the Smart Control system, enabling real-time wear monitoring. Many users also sign service contracts to minimize unexpected downtime.

8. Superior Industries

Superior not only guarantees OEM crusher parts with original quality and stable inventory for its own machines, but has also expanded its aftermarket coverage through acquisitions, supplying replacement parts for Clemro, Raptor, and Metso HP cone crushers.

9. Eagle Crusher

Eagle Crusher’s advantage in North America is fast delivery and a strong service network. Its catalog covers wear parts and spares, with Rapid Kits (pre-packaged spare kits) for quick emergency replacement. For contractors, this immediacy often outweighs the unit price.

The value of aftermarket crusher parts manufacturers is not just “cheapness,” but flexibility and customization. They can supply across brands and models, and often provide alloy solutions not available from OEMs.

• CMS Cepcor (UK) → The most recognized global aftermarket supplier, with broad inventory even for legacy brands like Telsmith and Kue-Ken.

• Columbia Steel (USA) → Specialized in custom profiles. Buyers can order specific tooth designs or alloys based on material properties.

• Unified Screening & Crushing (USA) → Provides both screens and wear parts, a one-stop solution especially convenient for quarries.

• Cutting Edge Supply (USA) → Focused on heavy equipment wear parts, with wide stock availability.

• Mellott Company (USA) → A long-time authorized Metso distributor in the U.S.  However, Mellott also stocks and sells a wide range of OEM and aftermarket parts across multiple brands (Metso, Superior, McLanahan, Sandvik, etc.).  They also provide rebuild / service support and integrated parts solutions.

• Optimum Crush (USA) 
  Optimum Crush supplies cone crusher wear parts, including Raptor®, Telsmith, and custom components. With continuous R&D and ready-to-ship stock, the company helps mines reduce costs and maximize uptime.

Many older crusher brands are still running, but their OEM status has changed. Important notes:

• Some brands are discontinued, with no OEM support → only aftermarket suppliers (CMS Cepcor, PAJOA, etc.) can provide parts.
  
  

• Some brands were merged into new OEM groups → partial OEM support is still available via the successor.

By now, the market structure is clear:

• OEMs → Lowest risk, complete solutions.
  
  

• Aftermarket → Flexibility and customization.
  
  

• Legacy brands → Mostly rely on aftermarket or successor OEMs.

So the decision path is simple:

• ✅ If you want lowest risk → choose OEM (Metso, Sandvik, Astec, and other OEMs).
  
  

• ✅ If you manage mixed equipment or need cost balance → choose global aftermarket (CMS Cepcor, Columbia Steel).
  
  

• ✅ If you run legacy brands → aftermarket is your only path.
  
  

• ✅ If you want OEM-fit plus upgraded alloys → work with a sourcing partner (like PAJOA) who connects directly to foundries and delivers both.

In short: Choosing the right crusher parts manufacturer is about matching your equipment setup with the right supply path—minimizing downtime and maximizing value.

Whether you prefer OEM or aftermarket, the ultimate goal is the same: less downtime, more output. Knowing which crusher parts manufacturers provide what is just the first step — the key is turning this knowledge into the right procurement decision for your project.
